Converting MP3 to WAV unpacks the compressed audio back into uncompressed PCM samples. The file jumps from a few megabytes to roughly 10 MB per minute of stereo audio, and nothing about the perceived quality changes. WAV stores what MP3 decoded to.

This conversion does not restore quality that MP3 compression discarded. Artifacts baked in during the original encode stay in the WAV. What you gain is a format every audio editor and DAW accepts natively, with no decoding step at playback.
WAV plays natively on Windows, macOS, Linux, iOS, Android, and every audio application made in the last 30 years. There is effectively no device that can't open a WAV file.
MP3 is the most widely supported lossy audio format. Encoded in 1993 and still the default on countless devices, it trades some fidelity for dramatically smaller files. At 192 kbps most listeners cannot distinguish it from the source. Anything that plays audio will play MP3.
WAV is Microsoft and IBM's uncompressed PCM container. A stereo CD-quality recording takes about 10 MB per minute. Because nothing is thrown away and nothing is compressed, WAV is the universal working format for recording, editing, and mastering in every major DAW.
No. MP3 is a lossy format, so information the encoder discarded is gone. Converting to WAV gives you an uncompressed file of whatever the MP3 decoded to: no better, no worse.
Expect roughly 10× the MP3's size. A 3-minute song at 192 kbps MP3 is about 4 MB; the same audio as 16-bit 44.1 kHz stereo WAV is around 32 MB.

Yes. The converter runs entirely in your browser using FFmpeg compiled to WebAssembly. Your audio files are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Files over about 2 GB total can get slow or hit browser memory limits. Process in smaller batches if you run into issues.
